Re: [PHP] ASCII Captcha

CAPTCHA's don't work. Don't depend upon them for any of your projects.

Sure they do. My blog comments were getting spammed to death. Now I've
put a captcha on I rarely have to deal with spam. I'd say that's
working.

CAPTCHA's present accessibility problems for people with disabilities.

These can be alleviated by, for example, adding a sound option like
Recapture has. Not perhaps a 100% solution, but it does help
tremendously.

CAPTCHA's show the world that you really haven't thought this out.

Actually my captchas show the world some funky coloured text... :-)
